A Simple Lithium(I) Salt with a Microporous Structure and Its Gas Sorption Properties

Abstract

Aufnahmefähig: Durch Kombination von Lithium‐Kationen mit Isonicotinat‐ Anionen (1) erhält man ein Salz (siehe Bild; C schwarz, O rot, N blau, Li violett), das H2 , N2 , CO2 und CH4 reversibel aufnehmen und abgeben kann. Der Festkörper liegt als dreidimensionales Gerüst vor, in dessen Mikrokanälen sich Lösungsmittelmoleküle befinden.

Metal–Organic Frameworks Constructed from Group 1 Metals (Li, Na) and Silicon-Centered Linkers

“…One of the two independent L1 linkers generates the 8-membered ring and also contributes to stabilizing the cluster, whereas the other L1 linker is solely bonded to clusters. Polymeric annulated ring systems with alternating 8-and 4-membered rings have previously been observed in Li + MOFs, 10,15,19 and Bu and Feng recently observed alternating 6-and 4membered rings. 55 However, IMP-22 is the first structure containing tricyclic repeat units connected by a polyhedral cluster of Li + cations (Figure 3c).…”

“…Although a small number of coordination polymers with Li + -based nodes had previously appeared in the wider literature, 9 the first Li + -based MOF showing permanent porosity was not reported until 2010 by Abrahams et al using an anionic isonicotinate linker to give a porous MOF which demonstrated modest H2 uptake. 10 Since then, Li + -based MOFs have been reported using linkers as varied as amino acids, thiophenedicarboxylates, and anthraquinones. [11][12][13][14][15][16] These Li + -based MOFs have been shown to display properties such as luminescence, [17][18][19] gas uptake, [20][21] and even have potential applications as electrodes in Li batteries.…”

Porous Lithium Imidazolate Frameworks Constructed with Charge‐Complementary Ligands

“…[7–8] Nevertheless, to date, the framework based on only 4-connected lithium nodes remains unknown, even though Li-containing boron imidazolate frameworks and frameworks containing Li-O clusters or chains are known. [9] …”
